Are my female bettas males?

[Jemstar]

I purchased two female bettas over xmas, now they have grown they seem more like males, the red one i have def seen a white spot underside but bit confused if they just really fancy females or young males

I would guess the blue one is a female, but not sure about the red one if you have seen a white spot. :S Other people on the forum are more skilled at telling than I. Good luck!

The red one is definantly a male, and the blue one is a little hard to tell, but I think it is a male also.

Males can and sometimes do have a "white dot" on their under belly. So, that is not a good way of judging. But, if you look at the pectoral fins, you can see that they are longer then a females. The body shape is also different.
Here is an example of a female:
Not the best pic, sorry. But you can see her small/short pectoral fins.

Yeah I'd say the red ones def a male, not sure about the blue one though.

They both look like young males to me :) Just like my male fry.

The blue one looked exactly like my female, Clarise (only she was much darker.) As everyone else has said, the red one is a male, but I still think the blue might be a female...

Red one is a guy. Look for a longer anal fin.

I agree; red is a guy, but I think the blue is a girl. (S)he looks just like my Coral Belle. :)

Horizontal striping on the blue indicates that it is more than likely female.

She has a longer anal fin, but that horizontal stripe is a tell all.

Let me tell you though, It is getting frustrating seeing how many bettas out there sold as females turn out to be male.

Honestly, stress stripes have nothing to do with it. Young males often have those too.
